As of right now, the activity in the Gulf of Mexico is not a hurricane and it isn't expected to be a real threat to the oil spill activity going on. It is a Tropical Storm, the first named of the season for the Gulf/Atlantic, and while it is anticipated to increase in intesity, there doesn't seem to be any indications that it will be a problem for the Gulf Coast States, although it could still impact Texas should conditions change.
These are the latest forecasts and models:
The Jeff Masters blog indicates that the current forecast is for it to make landfall north of Tampico Mexico sometime late Wednesday or early Thursday morning as possibly a weak Cat 2 Hurricane.
Now based on what is being reported, as I said there isn't expected to be a real threat to the oil spill, but the storm is expected to generate wave activity that more than likely cause some problems for the skimming operations going on.
It is important to remember that things can change and drastically if weather conditions change so while this is the projected forecast, there is no guarantee that this is how this will play out.
I'll update if anything changes.
